帮忙解两个方程:①4x^3-4x^2+4x+2=0 ②4x^3+4x^2+4x-2=0 如果可以的话,
这两个方程都没有有理数解,只能用方程计算器(卡丹公式)了:
1)
X1=-0.342508031368075
X2=0.671254015684037-1.00460829647568i
X3=0.671254015684037+1.00460829647568i
2)
X1=0.342508031368075
X2=-0.671254015684037-1.00460829647568i
X3=-0.671254015684037+1.00460829647568i

X3=-0.671254015684037+1.00460829647568i
解方程:2/x^2+x+3/x^2-x-4/x^2-1=0
解方程4x^2+2x√(3x^+x)+x-9=0
解方程:(4/x-2)+(x-1/x-5x+6)+(2/3-x)=0
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解方程(3x^2+9x+7)/(x+1)-(2x^2+4x-3)/(x-1)-(x^3+x+1)/(x^2-1)=0
求帮忙解方程x²-2(x+3)(x-4)=0
